2007–2017年青藏高原东南缘贡嘎山峨眉冷杉林土壤含水量数据集

As the core of hydrological cycle of terrestrial ecosystem, soil water is an important carrier of the material cycle and energy exchange of forest ecosystem, and lays an important role in the hydrological processes and nutrient circulation of forest ecosystems. It is one of the important indicators for long-term observation of terrestrial ecosystem water environment. Pursuant to the protocols for standard soil observation and measurement of CERN, the Gongga Mountain station has been carrying out long-term monitoring of soil moisture content. This dataset collected and processed soil moisture content of mature Abies fabri forest, middle- aged A. fabri forest, succession forest of A. fabri and Populus purdomii, and the meteorological station of 3000 m. This provides data for understanding the soil moisture dynamic characteristics and its response to climate changes in this region. It is of great significance to the water balance, forest productivity, and ecological function maintenance of regional forest ecosystem.The dataset consists of one data file comprised of 1945 entries. It contains volumetric soil water content data of mature A. fabri forest, middle- aged A. fabri forest, succession forest of A. fabri and Populus purdomii, and the meteorological station of 3000 m.

土壤水作为陆地生态系统水文循环的核心环节，是森林生态系统物质循环与能量交换的重要载体，对森林生态系统的水文过程及养分循环发挥着关键作用，亦是陆地生态系统水环境长期观测的重要指标之一。依据中国生态系统研究网络（Chinese Ecosystem Research Network, CERN）的标准土壤观测与测量规程，贡嘎山站长期开展土壤含水量监测工作。本数据集收集并处理了成熟岷江冷杉（Abies fabri）林、中龄岷江冷杉林、岷江冷杉与川杨（Populus purdomii）演替林及海拔3000m处气象站点的土壤含水量数据，可为解析该区域土壤水分动态特征及其对气候变化的响应提供数据支撑，对区域森林生态系统的水量平衡、森林生产力及生态功能维持具有重要意义。本数据集包含1个数据文件，共计1945条记录，涵盖成熟岷江冷杉林、中龄岷江冷杉林、岷江冷杉与川杨演替林及海拔3000m处气象站点的体积含水量数据。
